"Peacocks can eat berries. In fact, berries are one of the favorite fruits for peacocks, both in the wild and when domesticated."
"Lucky for them, they can readily peck on berries and digest them. So, they typically experience no issues when they eat moderate amounts of berries."
"While they are not typically thought of as berries, Tomatoes and Bananas are actually berries."
"If you want a berry that will have minimal effect on your peafowls’ overall calorie intake, Tomatoes are the best."
